Connecting two Gallien-Krueger MB212?

[Theut]

Hi
This might be a reallyt stupid question, but is it possible to connect TWO Gallien-Krueger MB212 combos through their respective XLR-outs?
I love my MB212, but once in a while I would like a bit more headroom/power.
I've searched far and wide (here in Denmark at least ;-)) for the official - but unfortunately now disconitinued - GK MB extension cabs, which I know would be the best solution, but without any luck.
Best regards,
Mikkel

AFAIK it doesn't work that way. The Chain Out is out only. The MBP cabs had a Chain In as well as a Chain Out.

You could try a mono Y cable to split your bass's signal to both amps. It should work, but some amps hum when connected this way.

You could run one's XLR DI out into the other one's input. You'd need to EQ each amp, but you'd only need to figure out the right settings once

That kinda bites. Is the XLR mic or line level? Just about any powered enclosure should work. Do you actually have two MB212's? If so, I'd just buy a splitter box and call it a day.

I'll pile onto the "Splitter" bandwagon too

Many pedals with stereo output (some Delays, Chorus, and multis from Zoom) will have a left and right channel out already. You could get wonky results if you're running the effect in stereo, or it may sound great! I think you can use them as a splitter without having to run the effect in many cases. My Zoom MS-70CDR+ has this, and I believe you can either set it for dual mono or just have the same signal chain going through both outputs.

More expensive than just the splitter cable, but this could prevent unwanted signal attenuation I guess? Or give you a reason to buy some more bass gear

No, that won't work, it's a TRS breakout cable. A TS splitter wye is needed.

All XLR connectors on the MB212 are outputs, none are inputs.
Only the second generation MB ii combos have the Chain Out feature, and only the MBP powered extension cabinets have a Chain Input.
Your best bet is to use a signal splitter in front of a pair of combos, or get a bigger rig.

I used to run 2 MB115s from a stereo pedal.

Stereo pedal or this.

I don't know how well it would work in terms of balance, but I think you could go XLR out to 1/8" Aux in and get the same eq settings from amp 1.

 

[DanAdams]

A Reamp device would take the XLR Di output and turn it into a instrument level input to feed the next amp if that were a device that was more useful to you than a stereo pedal.

BUT, Just another bass cab would give you "a little more power" without all the complication.
EDIT: I just checked, I guess you cant do that on newer MB combos. I can on my older MB210.

You really won't gain headroom by connecting them.

Bass to a splitter (LEHLE P-SPLIT III: Passive splitter, DI box & reamplification tool) and from the splitter two cables to two amps. I do it this way.

?

Doubling the cabs and doubling the power should result in approximately +6dB more headroom.

I would suggest the Radial BigShot ABY for splitting your signal into 2 amps. It has features to do this well with out issue, and they come up used on Ebay

Won't work, summing in the aux input circuit will cancel the balanced output of the DI.

Sure you will, about 6dB of additional output level.

Years ago I experimented with using two combos simultaneously. (In my case they were two Ampeg "Rocket" amps, a 50W and a 100W, but that's probably irrelevant.) The "splitter" I used wasn't a simple Y connector: It was a pedal (in my case, a Sansamp) that had separate "affected" and "unaffected" outputs, which I sent to the two respective amps. This way, if you use effects -- especially any that tend to suck out the bottom end -- you can retain the full bottom end in one amp while adding the (bottom-sucking) effect to the other.

The only problem I had was that if the Sansamp was plugged in I got a nasty ground loop, but this was solved by unplugging it and running it on battery.
